#[non_exhaustive]
pub struct Put {
    pub item: Option<HashMap<String, AttributeValue>>,

Represents a request to perform a PutItem operation.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

item: Option<HashMap<String, AttributeValue>>

A map of attribute name to attribute values, representing the primary key of the item to be written by PutItem. All of the table's primary key attributes must be specified, and their data types must match those of the table's key schema. If any attributes are present in the item that are part of an index key schema for the table, their types must match the index key schema.

table_name: Option<String>

Name of the table in which to write the item.

condition_expression: Option<String>

A condition that must be satisfied in order for a conditional update to succeed.

expression_attribute_names: Option<HashMap<String, String>>

One or more substitution tokens for attribute names in an expression.

expression_attribute_values: Option<HashMap<String, AttributeValue>>

One or more values that can be substituted in an expression.

return_values_on_condition_check_failure: Option<ReturnValuesOnConditionCheckFailure>

Use ReturnValuesOnConditionCheckFailure to get the item attributes if the Put condition fails. For ReturnValuesOnConditionCheckFailure, the valid values are: NONE and ALL_OLD.

Implementations

impl Put

pub fn item(&self) -> Option<&HashMap<String, AttributeValue>>

A map of attribute name to attribute values, representing the primary key of the item to be written by PutItem. All of the table's primary key attributes must be specified, and their data types must match those of the table's key schema. If any attributes are present in the item that are part of an index key schema for the table, their types must match the index key schema.

pub fn table_name(&self) -> Option<&str>

Name of the table in which to write the item.

pub fn condition_expression(&self) -> Option<&str>

A condition that must be satisfied in order for a conditional update to succeed.

pub fn expression_attribute_names(&self) -> Option<&HashMap<String, String>>

One or more substitution tokens for attribute names in an expression.

pub fn expression_attribute_values( &self ) -> Option<&HashMap<String, AttributeValue>>

One or more values that can be substituted in an expression.

pub fn return_values_on_condition_check_failure( &self ) -> Option<&ReturnValuesOnConditionCheckFailure>

Use ReturnValuesOnConditionCheckFailure to get the item attributes if the Put condition fails. For ReturnValuesOnConditionCheckFailure, the valid values are: NONE and ALL_OLD.

impl Put

pub fn builder() -> PutBuilder

Creates a new builder-style object to manufacture Put.

Trait Implementations

impl Clone for Put

fn clone(&self) -> Put

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Put

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq<Put> for Put

fn eq(&self, other: &Put) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
